BENJAMIN C. SCHUTTE, OF HOOK, NEW YORK.

SPECIFICATION forming part of Letters Patent No. 762,661, dated J une14, 1904.

Application filed October 18, 1902. Serial No. 127,766. (No model.) 6

To all whom it may concern:

Be it known that I, BENJAMIN O. ScHnTTE, a citizen of the United States,and a resident of Red Hook, in'the county of Dutchess and State of NewYork, have invented certain new and useful Improvements in RegulatingMechanism for Sound Reproducing Machines, of which the following is aspecification. My invention relates tomechanism operated byspring-motors, and more especially pertains to said mechanism whenadapted to the requirements of sound-reproducing machines of the classrepresented in a general way by phonographs and graphophones; and theprincipal object of my invention is to provide an improved form ofduplicate brake mechanism to regulate the operative speed of thespringoperated gearing. By my invention I also provide an improveddriving-gear andin a general way an improved construction of mechanismfor devices of the class named. 4 The construction of the improvementwill be fully described hereinafter in connection with the accompanyingdrawings, which form part'of this specification, and its novel featureswill be defined in the appended claims.

In the drawings, Figure 1 is a reverse or bottom planview of a machineembodying the invention. Fig. 2 is an end elevation of the same. Fig. 3is a detail sectional view on the line 00 w shown in Fig. 1. Fig. 4 is adetail sectional view on the line y 3/ shown in Fig. 1. Fig. 5 is afragmentary View showing winding mechanism.

Corresponding parts in all the figures are denoted by the same referencecharacters.

The reference-numeral 1 designates the bedplate of the machine, securedto the under side ,of the lid 2 of the cabinet, within which themechanism is incased.

3 and 4 designate parallel brackets depending from the bed-plate andprovided at their ends with bearings 5 for the motor-shaft 6. Upon thisshaft 6 is mounted a cylinder 7, containing the springs for driving themotor. I preferably employ what is known as a triple spring motor,containing three springs; but as the motor proper, embodying thecylinder and springs, forms no part of the present invention a moredetailed description thereof is not deemed necessary.

Awinding gear-wheel 8 is mounted upon the shaft 6 at one end of thecylinder to mesh with a pinion 9, mounted upon a windingshaft 10, andconcentric with said wheel 8 is a ratchet-wheel 11, coacting with a pawl12 to prevent backward movement of the motorshaft. At the opposite endof the cylinder a driving gear-wheel 13 is mounted upon the cylinder orcasing 7 said gear-wheel meshing with a pinion 14., fixed upon a shaft15, supported in bracket-bearings 16 and 17, depending from thebed-plate.

Upon the outer end of the shaft 15, on the outer side of the bracket 16,is a gear-wheel 18, adapted to mesh with a pinion 19, fixed upon theouter end of a shaft 20, supported in bearings in the brackets 16 and21, depending from the bed-plate.

shaft 24, the latter being revolubly supported at its upper end in abearing formed in the bed-plate and adjacent to its lower end in abearing formed ina plate 25, secured to the bed-plate by a plurality ofparallel vertical arms 26. I

Fixed to the lower end of the shaft. 24 is a gear-wheel 27, meshing witha pinion 28 on a vertical power-shaft 29, said shaft 29 carrying at itslower enda gear-wheel 30, meshing with a worm 31 on the governor-shaft32. The governor-shaft 32 is supported in bearings formed in parallelbracket-arms 33 and 3 1, depending from 'the plate 25. A button orkeeper 35 is pivoted to the bracket-arm 33 and adapted to bear againstthe adjacent end of the governor-shaft to prevent longitudinal playthereof.

Upon the governor-shaft 32 is a fixed collar 36, connected on oppositesides by means of expanding springs 37 to the hub 38 of a disk 39, fixedupon the end of the governor-shaft and having a sleeve extension 40,formed with diametrically opposite slots into which extend pins 11,projecting from the shaft. On each spring 37 is secured a weight 37.

Fulcrumed to one side of the plate 25 ad- A bevel-gear 22 on' the innerend of the shaft 20 meshes with a bevel gear-pinion 23, mounted on adepending jacent to the disk 39 is a bell-crank lever 42,

provided at the end of its depending arm with a pad or shoe 43, ofrubber or equivalentmaterial, which isadapted to bear against the innerface of the disk.

The forward end of one arm 42' of the bellcrank lever 42 is connected toa screw 44, extending through an opening in the cover of the cabinet andis provided with a knurled knob 45. A spiral spring 46 surrounds the pin44 below the cover.

Projecting from the plate 25 is a sleeve or housing 60, Within which ismounted a brakeshaft 47, provided at one end with an arm 48, to which issecured a brake-shoe 49, of leather or like yielding material. Theopposite end of the brake-shaft 47 is connected to a lever 50, whichextends through an opening in the cover and frictionally contacts a flatspring 51, arranged on the under side of said cover.

The brake-shoe 49 is adapted to engage the rim of the disk 39, while thespring 51 is arranged to frictionally contact the brakelever and hold itin the desired position either in or out of contact with the rim of thedisk 39, according to Whether it be desired to stop or to start themechanism. It will be readily seen that the parts which control theoperation of the mechanism of the instrument may be operated by means ofthe members 45 and 50, which are readily accessible to the operator, andthat said parts are void of complication and certain of operation.

Power applied by the spring-operated cylinder 7 will be so communicatedby means of the gear-wheel 13, pinion 14, gear-wheel 18, pinion 19,shaft 20, bevel gear wheel 22, bevelpinion 23, shaft 24, gear -wheel 27,pinion 28, shaft 29, and worm-wheel 30 to the worm 31, thus rotating thelatter, and with it the shaft 32, carrying the pins 41, (one only beingshown). By means of the collar 36 the governor, comprising the springs37 and weights 37 is rotated with the shaft 32, and torsion of thesprings 37 is prevented by means of the pins 41, which engage in theslots which are formed in the sleeve extension 40 of the hub 38, towhich one end of each spring 37 is attached. The speed of rotation isregulated by means of the brakeshoe 43, which may be adjusted to variouspositions axially of the governor-shaft, said adjustments being effectedby rotating the screw 44 by means of the knob 45, the screw 44 eitherraising or permitting the spring 46 to urge downwardly, as the case maybe, the arm 42 of the bell-crank lever 42, thus moving the arm 42", andwith it the brake-shoe 43, toward or from the disk 39. When the governoris rotated, the weights 37 are cenquired position frictionally contactsthe disk 39 when the desired speed of rotation of the governor has beenattained, thus preventing the mechanism from attaining a greater rate ofspeed than the one desired.

I do not desire to be understood as limiting myself to the details ofconstruction and arrangement as herein described and illustrated, as itis manifest that variations and modifications may be made in thefeatures of construction and arrangement in the adaptation of the deviceto various conditions of use without departing from the spirit and scopeof my invention and improvements. I therefore reserve the right to allsuch variation and modification as properly fall within the scope of myinvention and the'termsof the following claims.
